My Signal control fuse keeps blowing leaving the machine totally without power to dash and starting. I have disconnect Signal switch on dash. But still blowing  any ideas.

If it is anything like the older Z's:

From my 2017 Z8 wiring diagram ...

That's the Ignition Signal line (15amps?). If that fuse blows, then no power gets to the engine kill switch, Fuel pump, EFI System, Starter relay, and it behave just as if the kill switch was on.


Of course, a Z950 wiring diagram would be a better resource.

Yep that's the one took all day but after discounting hazards and turning of headlights it worked. Plugged in hazards,  all ok , turned on headlights and it blew the fuse. Found a crack in the headlights and it had rained the night before. Who would think that this would kill the whole machine WOW! I thought the headlight fuse would have gone, anyway disconnected the cracked headlight and all is good.  less one expensive headlight and 5 fuses

What? A shorted headlight blows the ignition fuse?

I wish I had THAT wiring diagram, because that makes no sense at all.

Year and model?

having same issue here ! Is there any updates on a possible fix ?
